Couchbase disk performance vs MySQL
I intend to store quite a lot of data in the database (a few terabyes). Using Couchbase it can be quite expensive, because you need a lot of ram to store all the data. I wanted to know if I don't intend to use such high amount of ram, how the performance compared to MySQL. I just can't see myself paying for terabyes of RAM in order to work with high data capacity web application. Can you give me some insight?
